Silica Sand - an overview | ScienceDirect Topics
To make calcium silicate bricks, silica sand is mixed with high calcium lime at a sand–lime ratio of 10 or 20. The mix is then compressed into moulds and "autoclaved" at about 170°C (340°F) for several hours. Some gel, similar to the calcium silicate hydrate gel of the type that is formed by cement, is formed, and this bonds the sand particles together.

Silica sand - Sandatlas
Silica sand is a mineral resource. It is mined mostly for glass-making. Another major use of sand is a concrete production but that does not need sand to be as pure. Some beautiful beaches are made of silica sand. Beach of Siesta Key in Florida is especially famous for its white sand. Not all white sands are made of silica, though.

What is Silica Sand? (with pictures) - All Things Nature
A person sandblasting using silica sand. The most common mineral in the Earth's continental crust is quartz, and most silica sand is made up of broken down quartz crystals.Silica is another name for silicon dioxide, SiO2, of which quartz is a specific latticed structure. So silica sand is quartz that over the years, through the work of water and wind, has been broken down into tiny granules.

Pure Silicon Dioxide from Sand | Hobby Chemistry
As stated, Sand is composed of Quartz, among other things. The percentage of Quartz in sand differs greatly. On average, quartz makes up about 70% of sand. Quartz is a crystalline form of Silicon Dioxide. However, sand is not good to use in chemical experiments. First, because it is only 70% quartz (has a lot if impurities).
